LAM P.

. SPECIFICATION forming part of Letters Patent No. 409,086, dated August 13, 1889.

Apnlication filed October 3, 1888. Serial No. 287,100. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. WILDER,

. of Gardner, in the county of \Norcester and The invention consists in certain novel features of construction and combinations of parts of the lamp, including improved means for adjusting the wick and supporting the chimney, and allowing ready dismemberment of all parts of the lamp for cleaning or repairs, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a central vertical sectional elevation of the fount, burner, and a portion of the chimney of a lamp embodying my improvements. Fig. 2 is a plan View of the removable chimney-supporting ring and inner wind-guard of the lamp, and Fig. 3 is a detail sectional plan view taken on the line 00 0c in Fig. 1.

The oil-fount A of the lamp may have any desired size and design, and is fitted with the ordinary central tube or flue B, which receives air through holes din the lamp-base and conducts it to the point of ignition at the top of the wick C, which is preferably fitted around the outside of the air-tube and at its upper part passes between said tube and the inner tube or collar D of the burner. This tube D is fixed to the burner-base E, which is preferably formed with an inner annular depression 6 next the tube, and at its margin or periphery is provided with a depending flange or collar;

6, which is snugly but removably fitted to and preferably within an annular collar a, which is fastened to the lamp-fount and is preferably provided with an inwardly-projecting flange a which forms a support for the base and superstructure of the burner, and through them to the lamp-chimney, as hereinafter more fully explained.

Around the wick O is fitted or held in any approved way a clamp or clip ring F, by which the wick may be raised or lowered. This wick-ring is not new in or of itself; but I pivot to it, at g g, the opposite ends of a bent yoke G, which at its center is held to the lower end of a rod H, which is preferably made round and projects loosely through a hole 6 made in the top and outer part of the burnerbase E, said base being made somewhat larger in diameter than the upper portion of the burner. At one side the wick lifting or adjusting rod H is provided with teeth, forming a rack adapted to engage a pinion I, which is fixed to a shaft journaled to the burner-base E. lhe lamp-fount collar a is provided with a vertical hole a allowing downward passage of the pinion-shaft as the burner is adjusted to the lamp-fount and allowing removal of the burner with the pinion I, while the wickadjusting rod H remains in the lamp-fount and connected, as above described, with the wick-adj usting ring F.

It is obvious that if the pinionIis operated by turning the milled finger-wheel t' of its shaft the rod H will be either raised or lowered, depending on the direction of motion of the pinion, and as the rod is connected by the yoke G to the wick-ring the wick C will be either raised or lowered evenly and truly by the rod. It will be noticed that the lower end of the rack-rod H is connected to the yoke, and through it to the wick-ring at a point nearer the wick or the air-tube B than the hole 6 thus giving the rod a normal outward pitch or leaning from the bottom upward, and whereby as the rod is lifted by the pinion I or any other device the top of the rod will be caused to swing outward from the burner all the more as the rod is lifted; hence this leaning position of the rod allows it to be used without interfering with theupper works or chimney of the lamp and permits an ordinary bulb-chimney J to be used on the burner, as the rising rod will clear the chimney.

The lamp-chimney, which may have any preferred form, is supported directly upon a ICO ring K, which is sustained at a suitable height above the burner-base E by a series of elastic plates or posts L, preferably four, and having shoulders Z, on which the ring rests, and fixed in any approved way to the burnerbase or its collar 6. This ring K is preferably provided with a horizontal portion 7;, on which the chimney stands, and an upwardlyprojecting interior flange k, which the chimney fits at the outside, while the upper clamping ends Z of the plates L, which pass through slots or holes 10 of the ring, bear upon the outside of the chimney and hold it securely in place. The clamp-plates L thus would alone support the removable chimneysustaining ring K; but I give additional support to said ring by an outer perforated metal ring or band M, which is placed between the ring and the burner base-plate, and is preferably made separate from the ring K. This perforated ring M admits air to the point of ignition at the top of the wick, while preventing passage of sudden gusts of wind to the light, and may alone be used; but I prefer to also use a second or auxiliary perforated ring or band N, which has like purposes as an airsupply and wind-guard, and is preferably fitted snugly but loosely to the interior of the chimney ring K, and, as shown, extends within the annular depression of the burner base-plate E. These rings M N thus form a double wind-guard to prevent extinguishment of the light. The inner ring N is held concentric with the burner wick-tube D by the chimney-ring K, and the outer ring M is held concentrically by the chimney-ring supports L, or it maybe by the ring itself were it held to the supports otherwise than as shown in the drawings.

It will be noticed that in the preferred construction the air-supply and wind-guard rings M N-.one or both-and also the chimney- V supporting ring K, are all separable from the burner body or base and from each other, thus permitting their dismemberment to allow quick, easy, and convenient cleaning of all parts of the burner, especially the perforated rings M N; but the inner ring N may be easily cleaned were it fixed in some way to the chimney-supporting ring K to be rehaving an interior air-tube and wick and an adjusting ring or clamp device for the wick, ofa burner fitted to the fount and having a guide for the wick, a yoke pivoted at its ends to opposite parts of the wickring, and a rod connected to the yoke and passed upward through the base-plate of the burner, substantially as herein set forth.

The combination, with the lamp-fount having a burner and an interior air-tube and wick and an adjusting ring or clamp device for the wick, of a yoke pivoted at its ends to opposite parts of the wick-ring, a rod. connected to the yoke and provided with a rack and passed upward through the lamp-burn er, and a pinion journaled to the burner and engaging the rod-rack when the burner is adjusted to the fount, substantially as herein set forth. I

4. The combination, with the lamp-fount having an interior air-tube and wick and an adjusting ring or clamp device for the wick, of a yoke pivoted at its ends to opposite parts of the wick-ring and a rod connected to the yoke and normally leaning outward and passed through a guide-hole in the burner, substantially as described, whereby as the wick-ring is raised evenly by the yoke and rod the rod will be thrown outward at the top to clear the lamp burner or chimney, as set forth.

5. A lamp provided with a separable chimney-supporting ring and aperforated air-supply and wind guard ring made separate from the chimney-ring and placed loosely between it and the burner, substantially as described, for the purposes set forth.

6. A lamp provided Wit-h a separable chimney-supporting ring sustained by and above the burner, a separable perforated outer airsupply and wind-guard ring M, placed between the chimney-supporting ring and the burner, and an auxiliary smaller inner air-supply and wind-guard ring N, located between the ring M and the wick-tube of the burner, substan tially as herein set forth.

7. In a lamp, the combination, with its burner and shouldered posts or plates held thereto and forming clamps for the chimney, of a separable chimney supporting ring having holes through which the chimney-supporting posts pass and an inner upwardly-projecting flange to which the chimney is held by the posts, said ring resting on the shoulders of the posts and above the burner-body,substantially as herein set forth.

8. In a lamp, the combination, with its burner and shouldered posts or plates held thereto and forming clamps for the chimney, of a separable chimney-supporting ring having holes through which the chimney-posts o1 clamp-plates pass and an inner upwardly-projecting flange to which the chimney is held by the clamp-plates, said ring resting on the shoulders of the clamp-plates and above the burner-body, and a perforated air-supply and win d-guard ring placed between the chimneysupporting ring and the burner-body, substantially as herein set forth.

9. In a lamp, the combination of the fount A, having an interior airtube 1 a separable burner fitted to the fount and having ply and wind-guard rings M N, fitted around a base-plate provided. with a Wick ring or tube, the burner Wick-tube and between the burner 10 posts or plates L; held to the burner and proand chiinney-supportin g ring K, substantially vided with shoulders I, a separable ring K, as herein set forth.
